technical field

The present application relates to the technical field of terminals, and in particular to a mobile terminal.

Background technique

When the mobile phone is working, some data needs to be transmitted for a long distance inside the mobile phone. For example, the data of the USB port needs to be transmitted to the motherboard in the mobile phone, and the battery in the mobile phone needs to be crossed in the middle; The motherboard in the mobile phone needs to pass through the middle frame of the mobile phone, etc. At this time, it is necessary to bend the middle transmission channel.

At present, copper wires are often arranged in an FPC (flexible printed circuit board), and the copper wires are used as an intermediate transmission channel for signal transmission. Since the copper wire is easy to bend, the bending process of the intermediate transmission channel can be realized. However, in order to ensure that the copper wire does not break during the folding process of the mobile phone, the copper wire needs to be made thinner and can only be made into a single layer. In this way, when there are many signal channels, it is necessary to make the FPC wider, which is likely to conflict with the smaller scope of the overall machine architecture.

Contents of the invention

In the same principle, when the second signal area is a signal sending area and the first signal area is a signal receiving area, the signal transmission process of the two signal areas is similar to the above process. It can be seen from the above description that when the signals in the two signal areas of the mobile terminal are transmitted, the signal sources in one of the signal areas are aggregated and converted, and then transmitted to the other signal area through a flexible signal transmission medium.

Similarly, when the signal to be transmitted needs to be modulated by a digital signal to terahertz, and then the signal transmission between the first signal area and the second signal area is realized, the first signal transmission chip is a terahertz transmission chip, and the second The signal transmission chip is a terahertz transmission chip. No matter what kind of high-frequency electromagnetic wave is used as the carrier for signal transmission, the first signal transmission chip and the second signal transmission chip must be of the same type.

In the same principle, when the second signal area 3 is a signal sending area and the first signal area 2 is a signal receiving area, the signal transmission process of the two signal areas is similar to the above process. It can be seen from the above description that when the signals in the two signal areas of the mobile terminal 1 are being transmitted, the signal sources 5 in one of the signal areas are aggregated and converted and then transmitted to the other signal through the flexible signal transmission medium 4 area, which can effectively reduce the number of channels for signal transmission, thereby reducing the occupied space of the flexible signal transmission medium 4; and, the first signal conversion module 202 and the second signal conversion module 302 are connected through the flexible signal transmission medium 4, The connection reliability can be effectively improved, so that the signal transmission of the mobile terminal 1 is relatively stable, and the service life of the mobile terminal 1 is prolonged.
